The invention relates to the technical field of electric hoists, in particular to a chain type electric hoist which comprises a machine frame, a wire winding shaft is movably installed in the machine frame, the rear end of the wire winding shaft is rotationally connected with the inner surface of the machine frame, the front end of the wire winding shaft penetrates through the outer surface of the front end of the machine frame and is fixedly connected with a motor, and a controller is fixedly installed at the front end of the motor. Steel wire ropes are wound on the left and right positions, close to the middle, of the outer surface of the wire winding shaft, semicircular bases are fixedly installed at the bottom ends of the two steel wire ropes, hooks are hinged to the middles of the outer surfaces of the lower ends of the semicircular bases, and an aligning mechanism is arranged in the middle of the outer surface of the lower end of the machine frame. The influence of external factors on the two groups of steel wire ropes is reduced through the aligning mechanism. Crossing of two sets of steel wire ropes and swinging of the hook can be reduced, the steel wire ropes can be quickly reset after being crossed conveniently, operation danger is reduced, lubricating oil can be evenly coated on the surfaces of the steel wire ropes, maintenance of the steel wire ropes is enhanced, and working efficiency is improved.
本发明涉及电葫芦技术领域,具体为一种链式电动葫芦,包括机框,所述机框的内部活动安装有卷线轴,且卷线轴后端与机框内表面转动连接,所述卷线轴前端贯穿机框前端外表面并固定连接有电机,且电机的前端固定安装有控制器,所述卷线轴的外表面靠近中间左右的位置均卷收有钢丝绳,两组所述钢丝绳的底端固定安装有半圆底座,且半圆底座下端外表面的中间位置铰接有挂钩,所述机框下端外表面的中间位置设置有回正机构,通过回正机构降低两组钢丝绳受到外界因素影响。本发明能够减少两组钢丝绳的交叉及挂钩的摆动,方便钢丝绳交叉后快速归位,减少作业危险,可均匀对钢丝绳表面进行润滑油涂覆,加强对钢丝绳的养护,提高工作效率。
